Android中自定义textview可以进行自体设置

废话不说，下面是代码：

package com.windy.androidfont;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
    private Context mContext;
    private String TypefaceName = "";

    public String getTypefaceName() {
        return TypefaceName;
    }

    public void setTypefaceName(String typefaceName) {
        TypefaceName = typefaceName;
        Typeface typeface = Typeface.createFromAsset(mContext.getAssets(), "font/" + TypefaceName + ".ttf");
        this.setTypeface(typeface);
        System.gc();
    }

    public FontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.mContext = context;
        int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
        if (resouceId != 0) {
            TypefaceName = context.getResources().getString(resouceId);
        } else {
            TypefaceName = attrs.getAttributeValue(null, "typefaceName");
        }
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }

    public FontTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.mContext = context;
        // 先判断是否配置的资源文件
        int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
        if (resouceId != 0) {
            TypefaceName = context.getResources().getString(resouceId);
        } else {
            TypefaceName = attrs.getAttributeValue(null, "typefaceName");
        }
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }

    public FontTextView(Context context) {
        super(context);
        this.mContext = context;
        // TypefaceName = attrs.getAttributeValue(null, "TypefaceName");
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }
}

下面是布局：

<com.example.androidfont.FontTextView
        android:id="@+id/fontTextView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="69dp"
        typefaceName="pop"
        android:text="FontTextView"
        android:textSize="30sp" />
大字体是要设置的属性，pop是字体库的名字

注意：自体库文件我这里放到了assets中的font文件夹中给个截图吧：

strings.xml文件中的截图：可以把字体的配置放到字符串资源中，这样就能统一进行更改了，如果你的需要中要动态的进行配置的话，可以对FontTextView进行改写，我的想法是在将自体配置放进prefrence中进行配置，这样就可以直接在FontTextView中进行改写了，本来想把这个类写的完成呢，由于时间关系就没写，有需求的可以自己去实现。就说这么多吧。
